FOLDING LAMP-SHADE;

Specification of Letters Patent.

Patented Dec. 10, 1907.

Application filed February 25, 1907. Serial No. 359.079.

To all whom it may concern:

Be it known that I, VIoToR FREYTAG, a subject of the Emperor of Austria-Hungary, residing at Des Moines, in the county of Polk and State of Iowa, have invented a certain new and useful Folding Lamp Shade, of which the following is a specification.

The object of my invention is to provide a lamp shade of simple, durable and inexpensive construction so arranged that it may be folded to occupy a minimum of space for purposes of storing or shipping and also to provide means for holding the shade in its extended position, said means being' also adapted to sup ort the shade on a lamp globe to prevent t e material of which the shade is fprrkned from coming in contact with the g o e. 7

My invention consists in the construction of the folding shade and in the arrangement and combination therewith, of the devices for holding tion and for supporting it on a amp chimney out of contact with the lamp chimney, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawings, in which Figure 1 shows a perspective view of a lamp shade embodying my invention, shown in its extended position. Fig. 2 shows a bottom view of the lamp shade in its folded osition. Fig. 3 shows a plan view of the amp shade holder, and Fig. 4 shows a sectional view of the lamp shade supported on a lamp as in practical use.

Referring to the accompanying drawin s, the shade proper is formed with four si es which are inclined downwardly and outwardly. Two of the sides indicated by the numerals 10 and 11 are not folded or creased and may, if desired, be made of unyielding material. The other two sides 12 and 13 are creased from top to bottom at 14 so that they may fold inwardly, as shown in Fig. 2. These sides 12 and 13 are preferably made of stifi heavy paper or other suitable material capable of folding without breaking. The entire shade may, if desired, be made of a single piece of paper or other suitable matena the shade in its extended osi- In order to support the folding sides 12 and 13 in their extended position, as shown in Fig. 1, I provide two holders shown in Fig. 3, each made of a single piece of spring wire and having an inner V-shaped member 15 and an outer V-shaped member 16, spaced apartfrom the part 15. These holders are placed upon the sides 12 and 13, as shown in Fig. 1, with the material of said sides inserted between the parts 15 and16, thus leaving the adjacent ends of the holders projecting beyond the upper ends of the sides. These projecting ends are designed to engage the lamp chimney and thus support the shade upon the chimney. Obviously the holders may be adjusted relative to the sides to thereby adapt the shade to fit lamp globes of diflerent slzes or to permit the shade to be adjusted up and down on the lamp globe and held in different positions of adjustment. I do not desire to be understood as limiting myself to the material forming the lamp shade nor to. the particular construction of the holders shown.

I claim as my invention- 1. The combination of a lamp shade having two plain sides, and two sides provided with central creases or folds, and two spring metal holders detaohably and adjustably mounted on the folded sides to engage the creases or folds thereof, and to hold said sides rigid, said holders being designed to support the lamp shade on a lamp chimney.

2. The combination with a lamp shade, comprising two rigid sides and two sldes having longitudinal creases or folds, the sides being connected with each other and capable of folding at the connecting edges and two holders, each made of spring wire with an inner V-shaped portion and an outer V-shaped portion, said holders placed upon the top edges of the creased or folded sides with one member inside and the other outside, the adjacent ends of the holders projecting upwardly and toward each other to engage a lamp chimney.

VICTOR FREYTAG.
